Who is the armored titan?

The Armored Titan is Reiner Braun, a character from the popular manga and anime series "Attack on Titan." He is a Titan Shifter, a human with the ability to transform into a Titan. In his Titan form, Reiner possesses a thick, armored skin that makes him highly resistant to damage, hence the name "Armored Titan." He wields this power along with his fellow Titan Shifters, Bertolt Hoover and Annie Leonhart, to breach the walls of the Shiganshina District in the first episode of the series. Reiner and the other Titan Shifters are part of a hidden faction known as the "Warriors" who are sent on a mission from Marley, a nation across the sea, to infiltrate Paradis Island and reclaim the Founding Titan, a powerful Titan with the ability to control all other Titans.

Throughout the series, Reiner grapples with his dual identity as a Titan Shifter and a human, struggling with the moral weight of his actions and his desire to protect his friends and comrades. His story arc sheds light on the complexities of the conflict between Paradis Island and Marley, exploring themes of war, identity, and the sacrifices people are willing to make for the causes they believe in.

In his human form, Reiner is depicted as a tall, blonde-haired young man with blue eyes. He is initially presented as a friendly and compassionate individual, forming close friendships with his fellow cadets in the Training Corps. However, as the story progresses, Reiner's inner turmoil and conflicting loyalties become more apparent, highlighting the immense emotional burden he carries as a Titan Shifter.
